Description

A kind of paper knife tool rest

Technical field

The utility model relates to the five metals cutter and makes the field, more particularly, relates in particular to a kind of paper knife tool rest.

Background technology

Paper knife is a cutting tool relatively more commonly used, generally is used for the cutting of paper, cloth, plastic or other material.Now the paper knife of selling on the market generally is made up of blade, tool rest and handle of a knife, blade is positioned in the tool rest and can changes, and all be provided with on the tool rest locking blade locking device, difference according to locking device structure, various paper knives have very big-difference on the convenience of operation, therefore be necessary to improve the structure of paper knife, it is simpler to make it structure, more convenient operation.

Summary of the invention

The purpose of this utility model is in order to remedy the deficiencies in the prior art, and a kind of novel structure, easy to operate paper knife tool rest are provided.

The utility model is achieved through the following technical solutions:

The utility model is a kind of paper knife tool rest, and tool rest on handle of a knife, is provided with cavity in the described tool rest by the movable riveted of rivet, slidely connects sliding seat in the cavity, and sliding seat is provided with the screens of blocking blade.

Above-mentioned tool rest includes slice, substrate, inner layer piece and following sheet, four order stacks are fixed by screw, wherein go up slice and inner layer piece to have a position of bar shaped chute and two bar shaped chutes corresponding, the front end of substrate offers recess, and the width of recess, length are corresponding with width, the length of sliding seat.

Toward sunken inside, the darker one deck of the edges at two ends of bar shaped chute caves in whole stepped depression by the inner layer piece side at the edge of the bar shaped chute on the above-mentioned inner layer piece;

Above-mentioned bar shaped chute is by the past sunken inside in side of the close sheet down of inner layer piece;

Above-mentioned sliding seat one end has through hole, is equipped with push rod in the through hole;

Above-mentioned push rod is the cylinder push rod, is provided with cavity in it;

The position of the cavity arrival end of above-mentioned push rod is provided with a disk, and itself and push rod are one-body molded, and the diameter of disk is bigger than rod diameter;

Above-mentioned push rod is connected with spring, and the part of spring is goed deep in the cavity, and the other end contacts with following sheet.

Blade of the present utility model is loaded in the sliding seat, by promoting push rod push rod is moved along chute, drives sliding seat and moves in the tool rest cavity, reaches the purpose that is convenient for changing blade and locking blade.

Advantage of the present utility model is, compared with similar products, has novel structure, and blade can stretch out or take in the tool rest with sliding seat, and operates also very convenient, practical.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1, the utility model is a kind of paper knife tool rest, is provided with cavity in the described tool rest, slidely connects sliding seat 6 in the cavity, and sliding seat 6 is provided with the screens 61 of blocking blade.

Tool rest includes slice 1, substrate 2, inner layer piece 3 and following sheet 4, four order stack backs are fixed by screw, wherein go up slice 1 and inner layer piece 3 to have a position of bar shaped chute 5 and two bar shaped chutes 5 corresponding, the front end of substrate 2 offers recess 21, and the width of recess 21, length are corresponding with width, the length of sliding seat 6.Behind each sheet order closed assembly, last slice 1 and inner layer piece 3 substrate 2 is clamped, form cavity, sliding seat 6 sliding being loaded in the cavity in recess 21 parts of substrate 2.

The edge of the bar shaped chute 5 on the inner layer piece 3 is by the past sunken inside in side of inner layer piece 3 close sheets 4 down, and the darker one deck of the edges at two ends of bar shaped chute 5 caves in whole stepped depression.Sliding seat 6 one ends have through hole, are equipped with push rod 7 in the through hole.Push rod 7 is the cylinder push rod, is provided with cavity 72 in it, and the position of cavity 72 arrival ends of push rod 7 is provided with a disk 71, itself and push rod 7 are one-body molded, and the diameter of disk 71 is bigger than push rod 7 diameters, and push rod 7 is connected with spring 8, the part of spring 8 is goed deep in the cavity, and the other end contacts with following sheet 4.

Push rod 7 concrete mounting means are as follows in the present embodiment: push rod 7 is entered near the side bar shaped chutes 5 of sheets 4 down by inner layer piece 3, passes the through hole of sliding seat 6 then, puts in the bar shaped chute 5 in slice 1.One end of the spring 8 in the push rod 7 withstands down sheet 4 and push rod 7 is held out against disk 71 and inner layer piece 3 are close to, and disk 71 well is absorbed in the recess at bar shaped chute 5 edges, reaches good slip function.When the disk 71 of push rod 7 snaps in bar shaped chute 5 ends, therefore the depth ratio edge of locating to cave in is darker, push rod 7 will be stuck and can not slide, having the end that makes disk 71 eject bar shaped chute 5 by lower push-rod 7 by last slice 1 position only just can make disk 71 slide at the edges of bar shaped chute 5 smoothly, drive sliding seat 6 and move, reach the purpose of sliding and locking.
